in my Roadrunner '68 i want to change the original tire f70 14 .

i have in garage a set of cragar ss with Rim Diameter (in): 15 in.
Rim Width (in): 8.00 in cod .n CRR-61817 , well what size do you suggest me with this whhels without changing anyabout the fender or rear suspension?

i am thinking about 275/60-15 or 275/50-15....295 it is impossible...what do you think?

and the fornt tires?
245 it will be good?

thanks for your replay

enjoy with your mopar

 

It all depends on two factures.
1. Do you want a stock look? If so use 205/75/15 or 205/70/15 for the
front and the rear/

2. Or would you like the 1960-70's muscle car look? On my 1971 Charger
R/T, I have 235/60/15 on the front and 445/60/15 on the rear. The one
problem you will find putting the large size rear tires on the rear is space.
you will have to raise the rear-end up to get the clearance, (i.e. air
shocks with shock lift extentions or air shocks with spring shackles, or
cut and re-tub the rear fender wells. What I used was the first one so
that would be able to return my Charger to stock height when I needed to.
Best of luck.
